Hi, i have this in a my form for registration user <% fields_for "user[location_attributes]", @user.location do |location_form| %> <%= location_form.text_field :full_address %> <% end %> the location is required. and so if i submit the form without insert the location the instruction: <%= error_messages_for :user %> print: location required. but in the field there isn''t the div <div class="fieldWithErrors"> around the field of the location like the others fields required how i can connect the error of the location with the field: <input id="user_location_attributes_full_address" class="ac_input" type="text" value="" size="30" name="user[location_attributes][full_address]" /> thanks. -- Posted via http://www.ruby-forum.com/.
